NRC proposes changes to its rules on nuclear materials
In response to Executive Order 14300, “Ordering the Reform of the Nuclear Regulatory Commission,” the NRC is proposing sweeping changes to its rules governing the use of nuclear materials that are widely used in industry, medicine, and research. The changes would amend NRC regulations for the licensing of nuclear byproduct material, some source material, and some special nuclear material.
As published in the May 18 Federal Register, the NRC is seeking public comment on this proposed rule and draft interim guidance until July 2.

Two-group calculations of the propagation of neutron waves across an absorption discontinuity in beryllium are reported. The first slab is assumed to be of finite width, while the second is taken to be of infinite dimensions. It is found that in the first slab, the effect of the interface is felt earlier for lower frequencies.
